问题
I would like to observe the contents of a POST request whose successful completion results in a location.reload() - when I try to capture this request in the Network Panel of the Firefox developer tools, I find that the page reload clears the list of captured events. Can I prevent this clearing?
回答1:
From Firefox 31 onwards you can use the "Enable persistent logs" setting to prevent the Network Monitor from clearing the list on reload.

Despite knowing the name for the setting is "Enable persistent logs", it took me a while to find it on the settings page. I hope this helps:
回答3:
I couldn't find this setting in Firefox 57. The setting has been moved to the network tab itself, above the log table
